The RT9078 from Richtek is an adjustable LDO regulator supporting up to 3.3V output with 300mA current capability. Its standout feature is a 4µA quiescent current, making it exceptional for battery-powered and energy-harvesting applications. The 1x1mm ZQFN package is among the smallest available, ideal for space-constrained designs.
- Industry-Leading Low IQ: 4µA quiescent current maximizes battery life.
- Ultra-Compact: 1x1mm ZQFN package fits in the smallest devices.
- Wide Input Range: Operates from 0.8V, compatible with single-cell batteries.
- Good PSRR: 75dB at 1kHz reduces noise from switching regulators.
Energy Harvesting Systems
The 4µA quiescent current is critical for energy harvesting from solar or thermal sources, where every microamp matters for system efficiency.
Smart Meters
With 75dB PSRR at 1kHz, it provides stable power to metering ICs, ensuring accurate measurement in noisy grid environments.
Battery-Powered Remote Controls
The 1x1mm ZQFN package and low dropout enable slim remote designs with extended battery life.
Portable Medical Thermometers
Low quiescent current and compact size make it suitable for disposable medical devices requiring long shelf life.
Wireless Keyboards
Adjustable output up to 3.3V powers RF transceivers with minimal power waste during idle periods.
Sensor Tags
Ultra-small footprint and 4µA IQ allow integration into passive RFID tags for logistics tracking.
